Getting this error: attempt to index nil with 'UserId'

[248kt (lol)]

I’m trying to make a clicker game, but I keep getting this error

It says the problem is on ‘local playerUserId = “player_”…player.UserId’

game:BindToClose(function(player)
	for _, Player in pairs(game.Players:GetPlayers()) do
		
		local playerUserId = "player_"..player.UserId

		local tapsValue = player.leaderstats.Taps.Value

		local success, errorMessage = pcall(function()
			tapDataStore:SetAsync(player, tapsValue)
		end)
	end
end)

@248kt

game:BindToClose(function(player)

Not sure why you have a player variable declared here, but BindToClose does not pass any arguments.

@248kt

for _, Player in pairs(game.Players:GetPlayers()) do

In your for loop, you declared Player, NOT player, so you are referencing the wrong variable. Be careful of case sensitivity.
